I was wanting to buy one but the more I look at it, the more unappealing it becomes. The 30MB limit is kind of a turn off. Streaming longer samples was one of its highlights in my mind before I saw that. For $99 new though, it isn't too bad

Nothing available new as far as hardware goes. There are all sorts of used things of varying capabilities you could find in that range used. But a caution with older units is that they use older sorts of data storage materials like Smartmedia cards that may be a bit of a problem to find.

>>is there anything a bit more full featured for a similar price (between $100 and $200)? <<

if you have an iphone 4 or 5 (or a 5th gen ipod), the beatmaker2 app goes for $20. that plus an iConnectMIDI2+ ($120 with adapter) and a cheapo midi controller can work wonders (being a noob, you'll have a lot of questions tho)
